Regarding comment #11: I have tested both kernels provided with the following results: - 4.14 Bionic kernel (4.14.0-16-generic) does NOT exhibit issue #2 (missing files), but it does exhibit issue #1 (KVP daemon failure after boot).

[Kernel-packages] [Bug 1766857] Re: [Hyper-V] KVP daemon fails to start
I have tested Bionic with kernel 4.15.0-22-generic, linux-cloud- tools-4.15.0-22.24 and linux-tools-4.15.0-22.24 and both issues still occur. While testing the above mentioned kernel, I saw the following behavior: 1. Right after booting the system the KVP daemon reports it is active (running). The command "systemctl status hv-kvp-daemon" returns the following output: hv-kvp-daemon.service - Hyper-V KVP Protocol Daemon Loaded: loaded (/lib/systemd/system/hv-kvp-daemon.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2018-06-07 11:43:22 UTC; 55s ago Main PID: 1363 (hv_kvp_daemon) Tasks: 1 (limit: 4496) CGroup: /system.slice/hv-kvp-daemon.service └─1363 /usr/lib/linux-tools/4.15.0-22-generic/hv_kvp_daemon -n Jun 07 11:43:22 bionic systemd[1]: Started Hyper-V KVP Protocol Daemon.

After approximately 2 minutes the KVP daemon enters in the failed state (issue 1). 3. Manually starting the daemon with the command "systemctl start hv-kvp-daemon" works perfectly fine. 4. "systemctl status hv-kvp-daemon" will now show the second issue: hv-kvp-daemon.service - Hyper-V KVP Protocol Daemon Loaded: loaded (/lib/systemd/system/hv-kvp-daemon.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2018-06-07 11:47:29 UTC; 8s ago Main PID: 1995 (hv_kvp_daemon) Tasks: 1 (limit: 4496) CGroup: /system.slice/hv-kvp-daemon.service └─1995 /usr/lib/linux-tools/4.15.0-22-generic/hv_kvp_daemon -n Jun 07 11:47:29 bionic systemd[1]: Started Hyper-V KVP Protocol Daemon.

Rebooting the system after this point will no longer trigger the first issue, only the second one. Even stopping the VM and turning it back ON does NOT trigger the first issue again. Could it be that while the hv-kvp-daemon service shows the two files (hv_get_dns_info and hv_get_dhcp_info) are not found, it will not enter in the failed state? Meaning that the two apparently separate issues, are actually related. I am not 100% sure about this. In order to trigger the first issue again, the Integration Service corresponding to the KVP daemon has to be disabled and re-enabled, and the VM has to be rebooted. This is just the way I managed to reproduce the first issue again, I am not sure if there are other ways to trigger it again. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1766857 Title: [Hyper-V] KVP daemon fails to start Status in linux package in Ubuntu: In Progress Status in linux-azure package in Ubuntu: Invalid Status in linux source package in Bionic: In Progress Status in linux-azure source package in Bionic: Invalid Bug description: While testing Bionic daily build with kernel 4.15.0-20-generic we saw that there are 2 issues with the KVP daemon: 1.

[Kernel-packages] [Bug 1756129] [NEW] [Hyper-V] Dynamic Memory HotAdd memory demand increases very fast to maximum and logs show call trace messages
Public bug reported: Issue description: Memory demand increases very fast up to the maximum available memory, call traces show up in /var/log/syslog, the VM becomes unresponsive during the memory consumption, but it becomes responsive right after stress-ng ends its execution, therefore we can say the issue might be in the Dynamic Memory feature. Platform: host independent Distribution name and release: - Bionic (4.15.0-10-generic) - Linux Azure kernel (4.13.0-1012-azure) Repro rate: 100% VM configuration: Kernel: 4.13.0-1012-azure CPU: 8 cores RAM: 2048 MB Enable Dynamic Memory: Yes Minimum RAM: 512 MB Maximum RAM: 8192 MB Memory buffer: 20% Memory weight: 100% Repro steps: 1. Start the VM with the above configuration. 2. Run stress-ng with the following parameters: stress-ng -m 16 -vm-bytes 256M -t 200 --backoff 1000 3. In less than 60 seconds the entire memory is consumed. Additional info: 1. We also tested this on Xenial with default kernel and the issue does not occur. 2. The call trace message from syslog can be seen below.

[Kernel-packages] [Bug 1701222] Re: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services
I have tested the proposed kernel, but with this version both bugs are showing up. Could it be that the bug is not in the kernel, but in systemd?

I have tested the kernel provided with commit ef754413085f5 and the bug persists. The daemons do not stop if the integration services are being disabled. The kernel provided in comment #36 was not affected by the bug. That was the first good commit. Regarding comment #27, the kernel tested was reported as bad (the daemon still remains running after the integration service is being disabled). Just to make sure we got this right, there are 2 issues right now: 1. The daemons do not stop if the integration service is being disabled, they remain running in the process list, but are not functional. This issue is present in the kernels tested up to 4.4.0-2. This issue is NOT present in kernel 4.4.0-3, here the daemons processes do stop if the integration service is disabled. Regarding this issue, the kernel provided in comment #36 is a good kernel. 2. The daemons do not automatically start after the integration service is disabled and then enabled again. This is the initial bug discovered in 16.04 and 17.04.

[Kernel-packages] [Bug 1701222] Re: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services
The same happens on 4.4.0-20 kernel. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701222 Title: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services Status in linux package in Ubuntu: Triaged Status in linux source package in Xenial: Triaged Status in linux source package in Zesty: Triaged Bug description: Issue description: Hyper-V daemons fail to start after disable/re- enable VM integration services. Platform: host independent Affected daemons - KVP, FCOPY and VSS. Distribution name and release: Ubuntu 16.04, Ubuntu 17.04 Kernel version: 4.11.0-rc7-next-20170421 (for Ubuntu 16.04), 4.10.0-19-generic (for Ubuntu 17.04) Repro rate: 100% Steps to reproduce: 1.Start VM with Guest Services enabled (FCopy daemon starts automatically) 2.Go to File > Settings > Integration Services, uncheck Guest Services and apply (FCopy daemon will stop at this point) 3.Re-enable Guest Services from VM Settings (Fcopy daemon is not running). This is the issue. systemd monitors for the service and if we have the hook for the Guest Service, it tries to start the daemon again. systemd attempt to start any of the LIS daemons will fail, but manually executing the daemon binary, it will start the daemon. Additional Info: - the steps above can be repro'd with KVP / Data Exchange integration service as well. - Manually starting hv_fcopy_daemon works fine. - other distros (RHEL) does not have this behavior, the LIS daemons are started automatically by systemd once we re-enable the integration service. On the upstream kernel and the upstream hv daemons, these messages are recorded in syslog, once we re-enable the Guest service: HV_FCOPY: pread failed: Bad file descriptor systemd[1]: hv-fcopy-daemon.service: Main process exited, code=exited, status=1/FAILURE systemd[1]: hv-fcopy-daemon.service: Unit entered failed state. systemd[1]: hv-fcopy-daemon.service: Failed with result 'exit-code'.
